I am currently a student planning on entering the job market in 2-3 years, and I'm looking into some online courses relevant to my interests. I don't expect my current experience (astrophysics) to be directly relevant to a future employer, so I'm hoping to familiarize myself with the buzzword techniques of the business world. Most importantly, I expect to signal this extra-academia preparation to future employers down the road.
Particularly in the case of this machine learning course -- for which one can opt into a $79 fee for a "trusted, shareable certificate" -- does the certificate of completion significantly increase one's chances of receiving an interview, as opposed to simply listing the course on a CV?
The answer probably varies by field and individual business, but I'd like to know if these paid certificates are generally regarded as trivial or even if the certificate would become unimportant due to it being ~2 years old at the time of application.
Update 2 years later: I graduated with a Ph.D. in astrophysics and applied exclusively for data scientist positions in the months after graduation. Employers asked about my independent learning but never asked for certifications. Once I received their coding tests, the details of my learning were irrelevant to them; I received an offer for the position of senior data scientist at a U.S. manufacturing company, and it is going great. Best of luck to anyone reading this because they are considering a similar transition!
